Tipsily homes in on foolish talk (9)

I believe the answer is:

moonshine

I'm a little stuck... Click here to teach me more about this clue!

'foolish talk' is the definition.
(I've seen this before)

'tipsily homes in on' is the wordplay.
'homes in on' can be anagrammed to 'MOONSHINE'.
However, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for moonshine that I've seen before include "Smuggled alcohol" , "Illicit liquor - twaddle" , "Light in the still of the night" , "bunk" , "Smuggled liquor" .)

I've seen this clue in The Telegraph.
